Biometric and morphological features on magnetic resonance imaging of fetal bladder in lower urinary tract obstruction: new perspectives for fetal cystoscopy.

Ultrasound Obstet Gynecol 2020 Jul;56(1):86-95

EA 7328-PACT, Paris Descartes University, Sorbonne Paris Cité, Imagine Institue, Paris, France.

Objectives: Incompatibility between currently available fetoscopes and the anatomical constraints of the distended fetal bladder, with the resulting curvature around the bladder neck, account for most technical difficulties during fetal cystoscopy in lower urinary tract obstruction (LUTO). The aim of this anatomical study was to assess by magnetic resonance imaging (MRI) the variation in three bladder angles (bladder-neck angle (BNA), vesicourethral angle (VUA) and angle between bladder dome and posterior urethra (DUA)), according to gestational age (GA), bladder volume and the presence of LUTO.

Methods: From our fetal medicine database, we retrieved for review 46 MRI examinations of male fetuses between 2015 and 2019, including 17 with LUTO, examined at a mean GA of 28. Read More

Aggressive diagnosis and treatment for posterior urethral valve as an etiology for vesicoureteral reflux or urge incontinence in children.

Investig Clin Urol 2017 06 7;58(Suppl 1):S46-S53. Epub 2017 Jun 7.

Department of Pediatric Urology, Jichi Medical University Children's Medical Center Tochigi, Shimotsuke, Japan.

Vesicoureteral reflux (VUR) is one of the most common diseases in pediatric urology and classified into primary and secondary VUR. Although posterior urethral valve (PUV) is well known as a cause of the secondary VUR, it is controversial that minor urethral deformity recognized in voiding cystourethrography represents mild end of PUV spectrum and contributes to the secondary VUR. We have been studying for these ten years congenital urethral obstructive lesions with special attention to its urethrographic and endoscopic morphology as well as therapeutic response with transurethral incision.

Swiss Fetal Laser Group, University Hospital of Bern, University Hospital of Lausanne CHUV, Lausanne, Switzerland.

Fetoscopic coagulation of placental anastomoses is the treatment of choice for severe twin-to-twin transfusion syndrome. In the present day, fetal laser therapy is also used to treat amniotic bands, chorioangiomas, sacrococcygeal teratomas, lower urinary tract obstructions and chest masses, all of which will be reviewed in this article. Amniotic band syndrome can cause limb amputation by impairing downstream blood flow. Read More

The "flowerpot" sign: inference of poor renal function in high grade vesicoureteral reflux by calyceal orientation.

J Pediatr Urol 2015 Feb 2;11(1):31.e1-4. Epub 2014 Oct 2.

Children's National Medical Center, The George Washington University School of Medicine, 111 Michigan Ave NW, Washington, D.C. 20010, USA. Electronic address:

Introduction/objective: Modern radiographic advances have allowed for detailed and accurate imaging of not only urologic anatomy but also urologic function. The art of observational inference of subtle anatomic features and function from a static radiograph is being traded for new, more precise, and more expensive modalities. While the superiority of these methods cannot be denied, the total information provided in simpler tests should not be ignored. Read More

Laser ablation in the management of obstructive uropathy in neonates.

J Endourol 2015 May 5;29(5):611-4. Epub 2014 Sep 5.

1 Department of Urology, Columbia University Medical Center , New York, New York.

Introduction: Endoscopic management of posterior urethral valves and congenital ureteroceles is the current standard to relieve the obstruction. While the most commonly used techniques involve cystoscopic incision with cold knife or electrosurgery, an alternative is to ablate the obstructive tissue with laser energy. With increasing prenatal diagnoses, there has been an increasing shift in the timing of intervention toward earlier periods. Read More

Mitrofanoff for valve bladder syndrome: effect on urinary tract and renal function.

J Urol 2014 May 26;191(5 Suppl):1517-22. Epub 2014 Mar 26.

Birmingham Children's Hospital, National Health Service Foundation Trust, Birmingham, United Kingdom.

Purpose: Despite early diagnosis and valve ablation, progressive renal impairment develops in a significant proportion of boys born with posterior urethral valves. Bladder dysfunction is thought to have an important role in the etiology of this renal deterioration. We report the outcome of treating bladder dysfunction with clean intermittent catheterization and overnight drainage via a Mitrofanoff appendicovesicostomy with respect to upper tract imaging, urodynamic findings and renal function.
